The grain I have made this metal wool from metal of themetsl of which they are composed is sheets of from three to nine one-thousandths parallel, or substsntililly so,'witli the lengths of an inch thickness, the filaments being cut 70 of the filaments; and in suhstslitmlly to a width of about twenty one-thousandths same condition as ll 11GB the metal is in the of an inch. The thickness and width of the form of rolled thin sheets. The fibers are metal filaments are determined, respectively, produced by severing rolled thin sheet by the stock used and the cutrandmay be such metal in lines parallel, r su stsntizilly so, as to sdapt'the material to desired usesf 1'75 with the grain of the metsl. The thickness have above given dimensions of filaments of the filaments is theseme as the thickness produced by me. They may, however, be

When rolled The filaments are formed by passing a sheet thinshcet of metal is divided intos plurality of metal between opposed gangs of rotary of filaments by cuts parallel, or substantially circular cutters. The rotary circular cutters 30 so, with the grsin of the metal the grain is of the two gangs are smccd by circular not materially disturbed. The advantages washers respectively of tie same thickness oim metal wool of this character src: that as the immediately opposite cutter of the it does not crumble or hresr, cinch iilmncnt I other gang, and are so arranged thst the cutretaining the characteristics ol' the nstill in ters in one gong enter the spaces between 35 the original sheet, slthougrh who nn-tsil is 1 cutters in the other suilicicntly to insure that somewhat hardened liy tin: shearing Opfl'ilr' l contiguous edges of the cutters shcll'c0oper-.

Each cut therefore forms the contiguous edges of parallel filaments, there being as elastic or resilient rinislities of theshect from Insny filaments as there are cutters in the which. they are cut, such. a illltiGS being t q 10 slightly emphasized by the operation Qi cutting.
